Six different crude extracts from bark powder of an important medicinal plant, Acacia nilotica (L.) were investigated for their toxicity against Spodoptera litura (Fab.). Total phenolic content in six crude extracts was measured. Ultra-High Performance Liquid Chromatography (UHPLC) was also performed for qualitative analysis of six crude extracts which revealed the presence of 11 phenolic compounds. Bioassays conducted with all crude extracts revealed maximum adverse effect with acetone extract. Duration of larval period and total development period was found to be prolonged. Various aberrations were observed in pupae and adults in the form of wrinkled pupae, blackened pupae, bulged out head part of pupae, partially emerged adults and adults with crumpled wings. All nutritional indices viz. RGR, RCR, ECI, ECD and AD decreased with treatment. The findings indicated that A. nilotica had considerable potential in the management of this serious insect pest.
